Windows 10: I need help going from Legacy to UEFI so i can enable secure boot and update to windows 11

I am not a tech savy person, this is my first pc and I really don't understand the innerworkings. My computer currently boots with Legacy and its needs to become UEFI for secure boot to work and I know that I need to turn MBR to GPT. I went to the command prompt and typed in mbr2gpt.exe /validate and it says "This app cannot run on your PC". I am really just blind to this whole situation I have no idea what I am supposed to be doing I have just been frustratingly googling questions and trying to piece it all together. Any help would be very much appreciated.

Windows 8 Secure Boot Feature: Not So Secure?

So Linux is switching to secure boot also? Or they have to because of UEFI?

 

Windows 8 Secure Boot Feature: Not So Secure?

• Linux
• Linux
• Linux
• Linux
• Oh and OSX

Here is a statement from a Kernal Developer at Red Hat:

I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.

 

Unable to enable Secure Boot as UEFI BIOS is running in Legacy mode

I have Windows 10 Insider preview installed on a custom built PC with an ASUS M5A99X Evo R2.0 UEFI motherboard. The motherboard carries the Windows 8 ready logo, meaning it supports Secure Boot and has a UEFI BIOS.

When I installed Windows 10, I did not realise that the motherboard was actually running in Legacy Mode by default out of the box for the on-board devices i.e. the HDD, DVD USB are all running as traditional BIOS devices and not UEFI BIOS. Windows shows
that the BIOS is running in Legacy Mode and that Secure Boot is not supported.

If I go into the BIOS settings, I can see that the Secure Boot option
IS enabled, but Windows still shows that it is not supported. I tried changing the Boot devices to prioritise UEFI drivers first and reinstalled Windows (as a clean install is required if you want to enable Secure Boot), however Secure Boot was still
not enabled and Windows still it shows as the BIOS as running in Legacy mode. I then tried switching off Compatibility mode within the BIOS settings, however after doing this no boot devices were detected, so I could not attempt to install Windows 10 again,
either from USB or DVD.

Switching the compatibility mode back on allowed me to boot back into Windows.

I cannot find a way of turning off Compatibility Mode in the BIOS and still having boot devices available to install Windows from.

I have tried everything I can think of to get this working, but without success. I would like to have Secure Boot enabled as it is a important security measure and the reason why I purchased the motherboard I did when building my PC.

Please do not copy and paste replies asking me to disable my antivirus etc. or check for malware, then mark my question as Answered, as the Microsoft "helper" bots normally do!


Thanks!
